The Combined Effect of Short Term Green Tea Extract and a Single Bout of Cycle Ergometer on Glycerol and Free Fat Acid of Trained Males

Abstract

It seems that shortly after green tea extract (GTE) ingestion, fat oxidation increases as well as exercise training. The purpose of this study was to investigate the combined effect of short term GTE and a single bout of cycle ergometer upon post-exercise fat oxidation. Sixteen healthy volunteer males were recruited to participate in the study. They were divided to two groups; experimental group (n = 8) and placebo group (n = 8), respectively. They consumed three GTE or placebo capsules a day before and one capsule 90 minutes before a cycling protocol. Blood samples were collected from all participants before and after the protocol. Based on the current results, fat oxidation in the experimental group increased markedly during post-exercise period compared to the placebo group. Plasma glycerol levels of the experimental group were significantly higher after GTE consumption during the post-exercise period compared to placebo. Compared to placebo, plasma free acids of the experimental group increased significantly after GTE consumption as well as acute GTE. Therefore, it seems that acute GTE ingestion could increase fat oxidation after post exercise conditions.
